IMPROVEM ENT IN Tl RE-TIGHTENERS.

Specification forming part of Letters Patent No. 220, 345, dated October7, 1879; application filed August 9, 1879.

- sponding parts.

The object of this invention is to provide a device for tighteningwheel-tires by raising or spreading the fellies so that washers may beinserted between the ends of'the spokes and the felly or between theparts of the felly itself.

The invention consists in a device for tightening tires, consisting ofstandards, base provided with stud, screw, screw-nut, pivoted top andnut, and in a clamp provided with setscrews combined with the ti ghtener, as hereinafter described.

In the drawings, A A represent the standards, B the curved basecross-bar uniting the standards at the bottom and curved to fit upon thehub of the wheel. G is the screw-nut, in which the upper ends of thestandards terminate. D is the long upright screw, having fixed upon itsshank a nut, M, for the application of a wrench to turn the screw, and Eis the crescent-head of the device pivoted on the screw-shank.

To operate the device, its base is placed upon the hub H between thespokes I I, as shown in Fig. 1, and the head is set under and againstthe felly K, near the outer end of the spoke; then by extendingthe screwthe felly is lifted oli the spoke, so that a circular slotted washer, F,of hard leather or other suitable substance can be inserted between theshoulder of the spoke and the felly, thus tightening the tire L; andthis application can be made to two or more spokes should the treatmentof one not be sufficient.

Upon one side of the base of the device is seen a sharp projecting pinor stud, a, which is of service in the case of old wheels, in which thespokes are sometimes loose in the hub. In such cases the stud is made topenetrate and hold the base of the spoke and prevent it from drawingfrom the hub when the felly is being raised from the other end.

In operating on very old wheels, where the fellies have shrunk so thatthey do not fill the tires, I make use of two clamps, G G, furnishedwith set-screws b b, and these I fasten to parts of the felly at asufficient distance apart for the tightener to be placedbetween them, asshown in Fig. 3 then by the extension of the screw I force the fellyapart so that a washer may be inserted between their ends, thustightening all the joints in the felly and making it solid.

The instrument is simple, easily adjusted, and most ett'ective.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. The within-described device for tightening tires,consisting of standardsA A, base B, provided with stud a, screw-nut O,screw D, pivoted top E, and nut M, substantially as herein shown anddescribed.

2. The clamp G, provided with set-screws b, in combination with thetire-tightener, substantially as herein shown ,an d for the purposedescribed.
